Okay, since I’m an “old school-er”, these ones are all from the 70s.
1. Sammy the Snake (the one who looked and sounded like the letter “S”.) I still have a hard time watching Sammy.
2. The cartoon of the snake that talked about the “sound of the letter S”. You could only see his face during most of the clip, until the end when it’s revealed that he’s a snake.
3. David as a snake charmer (Is anyone seeing a snake trend here?)
. He is sitting between two baskets while playing a wind instrument. As he plays, the number 12 comes squiggling out of each of the baskets, like they’re snakes. I mostly couldn’t STAND the creepy factor of this clip because the music was so weird and David was so serious….
4. As mentioned before, the Dragnet “W” clip. Don’t know what scared me…. I think it’s cool now.
5. The morphing face cartoon. The clip shows a face that changes with a creepy squeaking sound in the background.
6. Beautiful Day Monster. Like Sammy the Snake, he gave me nightmares for years. In my opinion, the clip with the “B” was the scariest thing ever on Sesame Street.
7. Grover and the word "GROW". When it grew really big and exploded at the end, that was enough to scare the daylights out of me.
Same thing with the imaginary balloon bursting at the end of that classic E and B clip.
A lot of other clips made me feel uneasy, but those are the few that really scared me.
